Run. Hide. Seek.

Gemma Falls never expected to use her game-theory expertise to outrun a killer. For years that skill kept her one step ahead of a deadly stalker. A teaching post at D.C. University promises safe harbor for her and her young daughter—the only flaw is the arrogant philosophy professor always underfoot, giving unwanted advice in his sexy British accent.

Jethro Hanson has blood on his hands. His work with the Deep Ops team and the deadly acts he once committed for Queen and country place him beyond forgiveness—until he meets Gemma. When he discovers a threat fast overtaking her, he must choose between the redemption he seeks and releasing the ever-present killer inside.
